It sounds like a lot of fun. Have you considered using a well built mildly cammed engine with intercooled twin turbos? You will have a much greater streetabilty with potentially more power. Probably for about the same money too.
 
excellent! beautiful car, beautiful wheels! i want the same wheels for my 68 fastback, but with a custom offset front and back, they are about $550 each! LOL cant do that yet..
 
the motor was dynoed today. everything went well. the results:
with an indy 3x and dominator 961hp@6400 903 hp@5500 862tq@5500
with a ported mopar 337 and 850 4150 carb 855hp@6100 791tq@5500
I should have the dyno graph in a couple of days.

should be a lot of fun in my "street car"!!!

Nice results! That's a great tq number and you don't have to spin it very high either for peak hp. How high did you turn it on the Dyno? Just curious because mine made peak power at 7,400 and we spun it to 7,700 on the pulls. Also what fuel did you use?

It was spun up to 7000. It did not pick up any after the peak 6400. I too also like the lower peak rpm,s. Should help with valve springs and piston speed. Used Sunoco 110 fuel. You have a larger camshaft in yours correct? Could be why your Peak RPM was higher. I should have a Dyno graph soon I will post it when I have it
 
I don't remember what your cam
Specs were. Mine is .830" lift and 289 duration at .050". I will have to look tonight but I think it's on a 113 lobe seperation.
